Etymology

In English, this muscle’s name is the crosswise muscle of the chest. The Latin term transversus means “crosswise” and comes from Latin trans meaning “across, beyond, or through” and the Latin verb vertere meaning “to turn.” The word abdomen is of uncertain etymology. Two possible origins of this word are from the Latin abdere meaning “to stow away,” which the abdomen does to the digestive organs. The other possibility is that it comes from adipem meaning “fat.”
